See Figure 1 below for a schematic representation of the concept. Figure 1 VAV System Schematic 2 The VAV system works by automatically reducing or increasing the amount of cool air allowed into a space (zone).
Hope this is an easy one. Have some SDVQ 5000 series units installed. The units with scr electric heat work great. The on/off units do not. They came bare from Price, added VAV controller later. Sending 24Vac signal successfully to the reheat contactor, and I'm seeing voltage to the contactor. Heat won't kick in and I'm wondering if it's because airflow switch is not making.For this reason, the Price SDVQ terminal units with integral silencers are tested as one complete assembly, per the terminal unit test method ASHRAE 130.

Model XG-TH-500 is the simplest and most widely used VAV terminal unit. Its basic components are an insulated sheet metal box, round inlet damper, flow measuring device and a rectangular outlet. The primary function is to regulate airflow to an occupied space. The XG-TH-500 can come with a heating coil on the discharge of the unit to provide for reheat, when necessary.The Price FDC, series flow, fan powered terminal unit, is designed to supply air volume to the occupied zone in response to a control signal. Features such as advanced sensor technology, a wide range of product sizes and air flows, low sound levels, increased hot water coil selections, and innovative options establish Price as an industry .The LMHS-LC terminal units are a fantastic energy efficient alternative to the traditional LMHS single duct terminal unit. The LMHS-LC utlilizes a large casing, which accompanied with a hot water re-heat coil greatly reduces air pressure loss through the coil, increases heating performance, and in some cases reduces number of coil rows.
Then use the 1.08*(CFM)*(dT) to determine how much heat you are getting from the box. <-- where in this case dT is the difference between the discharge air temperature of the VAV and the room set point. This is different than the actual temp rise in the box. Increase your minimum air flow if you are not getting enough heat.Integral electric coils are available on Titus single duct and fan powered terminals. The heater design minimizes stratification and hot spots that can cause nuisance tripping of the thermal cutouts. Each complete terminal, with electric coil installed, is ETL listed and has been tested in accordance with UL standards. The box will have heat capabilities if it is a perimeter box. It could be done with electric heat or hot water (coil). If a call for heat comes from the zone, the box will throttle the damper back and use Plenum air with the fan inside the box engaging. .
